短波紫外线照射对韭菜采后贮藏品质及活性氧代谢相关酶的影响
Effect of Ultraviolet C Irradiation on Post-Harvest Quality and Reactive Oxygen Species Metabolism-relatedEnzymes in Leeks
摘要
Abstract
Post-harvest quality and reactive oxygen species（ROS） metabolism-related enzyme activities were analyzed in postharvest leeks after exposure to a level of 1.7 kJ/m2 UV-C（ultraviolet C） irradiation.This dose of UV-C irradiation significantly inhibited xanthochromia and rotting rate,and slowed the decline of chlorophyll in leeks,with only 19.47% of chlorophyll degraded in multiple UV-C irradiated leeks 8 days after treatment compared with 30.53% in the control.The losses of protein,total phenols and other nutrients were also reduced by the UV-C treatment.The activities of CAT,POD and SOD were higher in UV-C treated leeks than the control.In conclusion,the data obtained suggest that UV-C irradiation is a potential strategy to improve post-harvest quality of stored leeks.关键词
